Hidden Dangers of Transient Low Voltage

In the environment of certain industries, the system power of equipment may suddenly become unstable; if this continues, the system may crash or there may even be damage to SSDs or loss of important data: 

Loss of existing data:

SSD can no longer be identified by the system, so its firmware may need to be reinstalled or updated, and its mapping table may need to be rebuilt in order for the SSD to be restored. In this instance, existing data can no longer be saved. 

Loss of cache data:

Data in the cache memory of the DRAM or data in the cache of flash is lost, causing loss of important data. 

Early scrapping:

SSD has large numbers of “new bad blocks." The health of the SSD is reduced, therefore, purchase cost is increased.

A⁺ Power  - Voltage Stabilization Technology Delivers Unrelenting Performance   

ADATA A⁺ Power technology protects SSDs that are in unstable power environments through its power circuit design, so that system performance will not be affected when voltage oscillates between 5.5V-4.5V, always maintaining efficient and stable operations, and prevents interruption of data transmission.

Triple Protection Improves Various Facets of Data Protection Mechanisms   

A⁺ Power 

When transient voltage oscillates between 5.5V-4.5V: 

The system’s power voltage is detected in real-time through power circuit design to ensure that the SSD always operates efficiently and in a stable manner.

A⁺ Power Protect

When voltage drops from 3.3V to 2.7V or 2.8V: 

SSD controllers are actively notified to cease new write instructions immediately through voltage detection circuit (VDT) and voltage-stabilizing circuit designs. 

PLP - Power Loss Protection 

When voltage drops to 4V: 

The PLP mechanism is activated and power is reserved through tantalum polymer capacitors; data in the cache has 75 milliseconds to be written into flash, completing preparations before power loss.
